What is Visual Dyslexia?
Dyslexia is a reading impairment that can result from an abnormal developmental process. While dyslexia has its core in a disruption of language processing, some believe that it may be a visual disturbance.
Some dyslexics complain that small letters appear to blur and move around when they're trying to read, leading to research being done in the field of optometry to see if there is a visual component to dyslexia.
What does the test involve?
A visit to your optometrist should be among the first things you do when your child or yourself is struggling with reading, regardless of what the ultimate cause might be. At a minimum, the assessment can rule out near and far sightedness. Of course tests of vision are even more important if you suspect that visual stress may be a factor.
Our optometrist is a specialist in visual stress and are able to conduct an assessment using coloured overlays and/or tinted lenses. The assessment may involve the use of an Intuitive Colorimeter, which helps identify the precise tint that best reduces visual stress for the reader.
Below is a summary of the most common and effective forms of intervention for vision related to reading difficulty.
Glasses: In some cases the problem will be solved through a pair of corrective glasses or contact lenses from the optician.
Coloured Lenses: Coloured lenses are just like a pair of sunglasses except with a carefully chosen tint that reduces visual stress for the person wearing them.
Coloured Overlays: Overlays are thin tinted sheets or transparent plastic that is placed over the top of any material being read, serving the same function as the glasses.
